    Actually very good quality I love it and I’m a pretty hard person to please.

    Reliable and high quality

    Both cables are reliable and high quality. I use Sennheiser IE600 and the connectors are accurate. Perfect. Delivered to the Czech Republic

    Great quality. Very well put together. The upgrade is well worth the money to spend on the 8 braid.

    Très bon cable

    J'avais déjà un lune et c'est ici mon second. Associé avec mes IE600, celui ci améliore notamment l'image du son par rapport au cable stock. Je recommande

    Lune series

    The Lune series upgrade cable made a marked improvement in the SQ of my MEST MK III IEM, opening up the sound quite a bit compared to another basic aftermarket copper cable . The improvement was not small. Resolution and imaging were noticeably improved. I used to be extremely skeptical about the possible effects of cables on SQ, but no more! Aside from the SQ boost, the cable is very nicely built, and gorgeous to look upon. Couldn't be happier.

Satisfying custom cable

Very sturdy 8W for my qdc iem, it does feels bit heavy on ear. For the sound I can't really tell big differences, I choose lune because of silver cable.

Lune Series MKVII Premium Upgrade Cable for Headphone | IEM

1st timer of using balanced cable. I must say the workmanship is top notch and aesthetically looks better than my stock cable. The cable elevates the sound quality produced from the DAP. The purchase is also generously included with Null Audio Grey Leather IEM/CIEM Pouch. Satisfied with the purchase.

null audio for the first time. I liked the product quality.

Kyungmo O. (Seoul, KR)
Highly recommended

I have several IEM cables for each IEM.
But this, Lune MKVII, cable is aesthetically beautiful and sounds great.
Furthermore, it has variety of options to choose specifically including flat 2pin.
After this satisfying purchase, I already bought another Null audio IEM cable in South Korea.

Lune mk7 = Referce Sound

tone balnce perfect.
8 wire is best choice.
Is it possible make mini-cable(3.5 auc)?

K
KIM (Gwangyang-si, KR)
Good cable!! Lune MK7!!

The thickness of the core increased compared to MK6, and the actual covering became thinner. So compact!!
As expected, the sound makes the mid-pitched range alive, and MK6's high-pitched notes seem to have cleared up.

great cable for premium iems

It instantly changed sound on my Audeze Euclid. Wider sound stage with detailed mids and bass. I love it.

ER4XR/SR adapter is unwieldy

Bought the Lune cable terminated with ER4XR/SR connector and it was not great. The headphone adapter used is very large and long, turning the already long IEM into an extremely long one when worn. It is actually very uncomfortable to use this without wearing over the ears, and when worn over the ears, it sticks out far further than the default cables.

On the bright side, the rest of the cable handiwork seems to be good on initial impression.

Users buying with headphone ER4SR/XR termination beware of this caveat. I would assume this applies for the other cables too since the headphone termination should remain the same.

Attaching an image comparing the extra length that Null Audio's ER4XR/SR termination adds compared to the original cable.

Hi End IEM cable

It is clearly not as warm. The upper treble is smooth; it’s a high resolution cable, very engaging for Jazz or Pop

Null knows how to make a cable

This is my second custom cable from Null Audio. I also own an Ethos 3. The Lune is fantastic. It's a good, sturdy, supple, soft cable. The splitter and termination are extremely light and still feel like metal (I think it's aluminum). I was nervous I would like the gold/silver colourway of the new Mark. IV's, but in real life, it's subtle, understated and classy. In terms of sound, the Clears already quite dynamic, so the difference in sound was minimal on a CTH, but still a great improvement over the stock cable for my Focal Clears!

Null Audio Good

I had fun buying a rune cable and listening to music. I think I was good at choosing a 2.5-balanced terminal and an 8-core cable while clearly separating vocals and instruments.

Hilton F.d.A. (Rio de Janeiro, BR)
A wonderful cable! I love it!

It is a wonderful product, it fits my A3H AAW perfectly and offered a very luxurious look. My only sadness is not about the product itself, but about my personal choice. I chose the 8 braid cable, which is beautiful, but much heavier than a 4 braid.

Elegant, Beautiful, Sonic Perfection - Even More Service Perfection

Where can I begin to praise Null Audio? The Lune MKVI is my THIRD cable from NA. So, that already tells you how much of a loyal fan I am - and this is the cheapest one I bought from them, yet, it is a perfect marriage with my Solaris. Once you get something from NA, you simply cannot go back to some other US brands. There simply is no comparison how much better NA's cables are. Not only do the sounds open up, but the craftsmanship (hand-made) takes this cable to a whole new level. I recommend the 8 braid upgrades. I can simply stare at the cable for 30 minutes to praise the work of ark. And then, you always have the confidence that this stuff won't break. Now for what makes Null Audio truly special - the amazing family-like service. I had a 10% off coupon which I forgot to use and I was going ton traveling in 7 days. I ordered the cable, told them I had the discount which I didn't apply. Guess what happened? A free upgrade of cable metal hardware from the Symphonym series (of which I own two - and I know they are the ones in my Lune MKVI). Not only that, I politely asked, if I can get this within 5 days (and I am talking to Su and the team all the way from US while they are in SG). 4 days later, wallah - Fedex International Priority knocks at my door. Now, is this service or what? THIS IS FAMILY! RESPECT TO NULL AUDIO!

Happy sound with great build quality

I used to use the fifth generation before.
In contrast to that clean sound, I bought the sixth generation and was very satisfied.
The previous generation has also been very good at sounding clean, light, and accurate,
but this product added a little bass to it.
The bass, which is never excessive or irritating, sounds like a wave.
The clarity and cleanness confine me to this cable.

Pretty good stuff! (Upgraded to Lune MKVI)

I have used it for over 2 weeks now. The cable I have is the MKVI, with mmcx connectors and 3.5mm balanced jacks with mic. Here's my thoughts.

First of all, packaging is awesome. A nice pouch, a good box. 'Nuff said.

Cable is a little thick, as promised. But that means it will be heavier, so it will be good to keep that in mind. Cable is sturdy and quality of the wires are good. I like the white chrome mmcx connectors which goes well with my clear SE846. No issues with the connection.

The only issue I have, is that the jack and center splitter casings are made of metal and are quite big. They do look nice, but they add significant weight to the cable, which makes it less comfortable on the ear. If there was an option, I would prefer even plastic casings or thinner metal to reduce weight. Since the wires themselves already aren't thin, it will be best if the other parts can be made of lighter materials to reduce weight. (Obviously the coolest material to use is carbon fibre)

Overall, I'm satisfied but there are still areas for improvement. Long-term performance has to be tested as well.

Will your ER4XR connectors fit the ER2XR and How well does the cable suppress the microphonics?

Null Audio

Yes, the ER4SR/XR option fits the ER2XR. Cable noise when walking mostly comes from the Y-splitter tapping your chest; clipping the cable to your clothing reduces it.

Null Audio

Yes, the ER4XR connectors will fit the ER2XR.
Both the ER4XR and the ER2XR utilize the exact same proprietary, customized MMCX connector with a locating tab (or "key") designed to lock the cable into place and prevent rotation.

Questions

Good to know

How long until it ships?

Every Lune Series MKIX is built to order by hand in Singapore. Lead time is around 1 week.

Will it fit my earphones?

Choose your connector when you order. FlexiPlug lets you switch between 2PIN, IE300, A2DC, IPX, Pentaconn Ears and QDC 2PIN. If your earphones are modified or need a custom fit, contact us before ordering.

Find the right connector for your earphones

Can I get a different length?

Yes. Choose Cable length in the configurator above: set any length from 50 cm to 3 m in 2 cm steps. Up to the standard 1.2 m costs nothing extra; longer cables cost more, and the price is shown before you add to cart.

For a length over 3 m, contact us or WhatsApp +65-8731-5476.

Will the cable turn green or yellow over time?

It’s built not to. Lune’s internal braids are individually insulated with a PVD-deposited clear coating for an extra layer of protection from oxidation, and the ultra-clear, soft sleeve is yellowing-resistant.
